Brain-behavior correlations: Two paths toward reliability

Caterina Gratton et al. Neuron. .
Free article

Abstract

In a recent issue of Nature, Marek et al. (2022) demonstrate that cross-sectional brain-behavior correlations are often small and unreliable without large samples. This observation pushes human neuroscience toward study designs that either maximize sample sizes to detect small effects or maximize effect sizes using focused investigations.
